Response of Forage Grasses to Rhodesgrass Scale

Abstract

Yields of 38 species of native and introduced grasses were found to be significantly reduced by scale infestation. Grasses are grouped into three classes: (1) grasses with reduced yields, (2) grasses infested but not affected and (3) resistant grasses. Twenty-eight new hosts of rhodesgrass scale are recorded. The data indicated that rhodesgrass scale is of economic importance in south Texas.
